The word slot has many different meanings. It can refer to a wide depression, narrow aperture, perforation, or hole for receiving a piece or sliding something in or out. SLOT is also a synonym for the word “deer track.” A bloodhound tracks the path of a wounded deer by following a “slot” in its neck. Some slots are narrower than others, but they all have one thing in common: they are all hollow.

The name slot refers to a small area of ice between the faceoff circles. It can also refer to two places in the rink: a low slot, where a puck is thrown in front of the goalie, and a high slot, which lies in the middle of the ice, above the faceoff circles. The high slot is often the target of an ice hockey player’s wrist shot. A good shot from the slot is one of the most effective shots in the game.

A custom slot type can be defined in the Utterance tab. There are built-in types and built-in ones. You can add a prompt and a slot, too. Values in a slot should be extended ISO-8601, for example. A built-in datetime type maps date and time values to slots in the same way. A custom slot type is an option that lets you define the types of values you want to map in the slot.
